Following are a number of back-translations as well as a sample translation for translators of Isaiah 59:2:

• Kupsabiny: “It is only your mistakes
  that are separating you from God.
  Your sins make God turn his back on you
  so he does not hear when you call him.” (Source: Kupsabiny Back Translation)
• Newari: “But because of your sins
  you have become separated from God.
  And because of your sins his face has been hidden from you.
  so that he does not hear your words.” (Source: Newari Back Translation)
• Hiligaynon: “Your (plur.) sins are the ones-who-separate you (plur.) from God and (it is) the reason that he turned-his-back from you (plur.) and no-longer listen to your (plur.) prayers.” (Source: Hiligaynon Back Translation)
